Answer 2

Answer:

TRUE

Explanation:

Friction arises due to the interlocking of hills and valleys present in a body.

No solid surface is perfectly smooth. There are present hills and valleys on the surfaces. When a body (say a wooden block) is pulled over another surface, these hills and valleys interlock with each other and oppose the relative motion between the two bodies. This gives rise to the frictional force. Thus, friction is due to the roughness of the two surfaces in contact with each other. More the rough surface, more the irregularities and more the friction present.
